Single Top Physics at the University of Toronto 
|
In 1995, the CDF and D0 collaboration discovered the top quark at the Tevatron collider at Fermilab. The top quarks were pair-produced via the strong force in quark-quark annihilation or gluon-gluon fusion processes. However, according to the Standard Model, the top quark can also be produced singly, in association with a b quark through an electroweak vertex. The two dominating processes at the Tevatron energies are the t-channel process (Wg) and the s-channel process (W*). With a cross-section about 40% of the QCD pair production mode, CDF in RunII has the sensitivity to discover Single Top.
